Our invention relates tochutes or plpes made of wood and more particularly to such.

chutes or pipes as are composed'of longitudinal staves, held in positionl byLa band sur'- vstaves abut.

rounding the barrel of the chute pr pipe.

The object of our invention, is to form an improved joint between'the abutting ends of two staves and to provide an improved form of clip whereby the band which Yencircles the barrel of the chutemay be more easily applied andbe of cheaper construction. 1 In the drawings, in which like letters indi` cate like parts, A, indicates the longitudinal stavesmade of'concavo-convex shape. j In Fig. l isshown the joint made where two As is seen,l the ends of the staves, are cut o at an angle of about fortyiive degrees with the edge, so that the two ends will iit into each other, and when pressed together will act to .wedge each other outf. ward. We may cut slots in the two inclined ends as shown, and insert therein a strip C, of galvanized iron or wood. Heretoforethe joints made in this class of work have been either butt joints, that is joints made at rightv angles to the longitudinal edge of the stave, or dovetail joints, where a dovetail recess is cut in both Y' ends of the abutting staves, and a double dovetail pieceof wood is inserted,in therecess and between the ends of the staves. The butt jointis not tight,

Vstaves are brought more closely together and *barrel of the pipe.

lthe hoop-rod D, has a head E, andthe other end is provided with screw threadlsQE,....I preferably make the band D, of rou'I Idfsfec` serial No. 478.394. (No modem .and cannot be tightened by any means after the chute or pipe is in position. With the dovetail joint, the dovetail swells,-and is very likely to split the wood, besides being costly compared with ourjoint. Withour improvement, the more the wood swells the tighterv the joint grows, thetwo pieces acting against' each other with a -wedging action, and not ,only does the endjoint grow tighter itself, 6o

but the wedging action also tightens the longitudinal joints. The round band D, orhoop, `which passes around the barrel of thepipe, to hold it together also has a function in connectionv with the ljoint which such bands have never had before; `As the band or hoop is tightenedf-as will bemore fully described hereinafter,the inclined ends of the wedged in. I

As stated above, the band D,surroundsthe In Fig. 4. is shown our improved clip by which the two ends of the hoop or band are held together. Oneend of tion though it might be made fiat with roundled vends.

p The-clip F, is made of cast iron and its in- 8o side surface is rounded to conform to the outside surface of the pipe or chute. The y upper end of the inside surface is slotted as at G, andthe slot has at its lower endan en-k largement G2, which vis adapted to fit vthe head E. The inside face Gof the slot G, is substantially parallel withthe inside face of the clip so as to hold the bandjor hoop D, at

fa slight tangent to the face of the stave A.

The recess G2, is rounded, topconform to the 9o rounded head E. The outside face ofI the clip, has aV longitudinal slot H, running its entire length, the inside face of which is at an angle of about forty-five degrees, with the vinside face of the slot G. l 95 The sides of the slot H, project outfarther at the upper end lof the clip, than at. the lower end as shown, formingwhat might betermed brackets. On the end of the clip and-surrounding the 'slot II, is`a countersink I, the Ico metal around the countersink forming a flange J. The washer N, below the nut L,

fits in this countersink, when the nut is in place, and the band D,drawntightly around the piping. The countersink and washer might be polygonal, though we prefer them round, and have so shown them.

In applying the band or hoop D, to the barrel of a chute, the head E, is first slipped into position in the recess G, G2 and the band passed around the barrel. Then the end E of 1o the rod-with the nut and washer in place,-

is sprung into the slot H, and the nut L screwed down, until the rod is tightened sufficiently, and the joints, both lateral and transverse are brought together.

In the clips as heretofore constructed, the end of the rod D, and head E,vh'ave been either cast in one piece with the clip or welded into it, and i-n place of the slot H, a hole vwas made entirely through the clip, through zo which the rod D has to be `threaded before the nut can be placed in positionand tightened, thus necessitating much labor and consequent expense which are done away with by our device. lf the clip wasbroken the z 5 entire rod had to be thrown away. If the rod was defective, the clip was useless. The nuts and washers had to be taken entirely off the ends of the rods, before they could be fastened in position, and the operation of thread- 3o ing the rods through Athe clips was troublesome and took time. With our improved clip, however, the clips may be cast separately, and put on the market separately, and defects inthe clip mean only its loss and not 3 5 that of the hoop rod, as well. It is much easier of construction and casting, than the old style there being no need of cores for the rod-holes, and withal it is very much simpler and quicker in its application, as will be read- 4o ily seen. The head E, as shown is rounded.

Heretofore this head has been square and rested in a square pocket in the casting. VSuch construction causes trouble in that the band D,

had to be turned and re-turned, until the head was in register, with the sides of the pocket,

or the head would only be heldin the castingy by the corners of the nut and not by its sides. Our construction obviates this, in that the nut and recess both being round whichever way it 5o is turned it is always in position.

4 We do not limit ourselves to the exact construction shown as many slightchanges might be made without departing from the spirit of our invention.

Our inventionmay be usedl in many constructions, such as waterl pipes, sluices, wasteways, and shafts beside that of 'a chute and we do not limit ourselves to its use in 'thatconnection.

Having described our invention, what we l. 'In a chute, a jointfor the meeting ends of two Vstaves, the joint being inclined to the longitudinal edge of two abutting staves, all as and for the purpose described.

2. In a chute, a joint for the meeting ends of abutting staves, the two staves being made-one with an upwardly and rearwardly inclined end, and the other with an upwardly and forwardly inclined end, the ends being adapted to it upon one another, vall as and for the purpose described.

3. In a chute, the combination, with an inclined joint between the meeting ends of two longitudinal staves, of a 'band surrounding the barrelfof the chute, and passing across the inclined joint, to hold the joint together, all as described and shown.

4. The combination with a rod or band Surrounding thebarrel of a chute, and provided with a head at one end, of a clip for joining the meeting ends of the rod, and consisting of a casting having on its under surface, arecess for the head,'and end of the rod, and on its outside face, a longitudinal slot for the reception of the other fend of the hoop or band, andA means for tightening the band, all as and for the purpose described.

5. As an article of manufacture, a clip for use in joining the hoops or bands surrounding'circularv chutes, consisting of a casting, having at one end of its inner face, a slot and an enlarged recess at the end of said slot, and on its outer face a longitudinal slot, the upper end of the clip having a countersink around the upper end of the slot, substantially as described.

6. As an article of manufacture, a clip for use in joining the ends of bands or hoops surrounding chutes, consisting of a casting provided at one end of its inner face, with aslot and enlarged recess at the lowerend of the slot, and on its outer face with a longitudinal slot, all substantially as described..

7. The combination, with a rod orband surrounding the barrelof the chute, one `end of the said rod having a head, the other end being screw threaded ,and lprovided with a-nut and washer, of a clip forconnectingthe meeting ends o f'fthe rod or band', the inner face of the clip being adapted'to lfit the barrel of the chute, and providedwitha slot'at its upper end, and an enlarged recess at the end of the slot to receive the head offt-he. band or rod, and the outer face of the clip having a longitudinal slotforthe reception of the screwthreaded end of the rod or band, and a flange or projectionupon the forward'edgeof the upper end of the clip, forpreventing the rod and nut slipping out of the longitudinal slot,

all substantially as described.
